PROBLEM TO BE SOLVED: To provide a gas turbine efficiently and reliably cooling and operating a combustor at partial load. SOLUTION: A gas turbine is provided with: a booster 40 which is connected to a branch flow path 42 branching off from a compressed air supply flow path 28 in a compressor 11 and which can be operated independently from the compressor 11 for extracting and boosting compressed air; a boosted air flow path 43 which leads the boosted compressed air boosted by the booster 40 to a combustor cooling flow path 50 provided in the combustor 12; and a boosted air return flow path 44 which leads the boosted compressed air passing through the boosted air flow path 43 to the compressed air supply flow path 28 to merge therewith, and carries out cooling by operating the booster to feed boosted compressed air into the combustor cooling flow path 50 when the gas turbine 10 is under partial load.
